Controled in the led by Arduino UNO to Firebase through ESP8266-01+ MIT App Inventor

Question

exchange community ,

help me community :(

I want to control led by MIT App Inventor with used Arduino UNO to Firebase through ESP8266-01

Notes :

1-The led connected pin 11 on Arduino-Uno

2-The esp8266-01 connected tx rx pin 2 pin 3 on Arduino-Uno

3- This circuit was designed by me, but I cannot control it through the Internet of Things

when I search on google i find this tutorial on YouTube but all video in google used dht sensor but i want controlled led :

enter link description here

this is dht sensor code :
